Intercellular adhesion molecule 1 (ICAM1) recombinant human protein is supplied as a lyophilized powder. This protein is suitable for use in performing cell based assays. It can also be used as a protein standard, or in other research applications.&line-break;Background: ICAM1 (Inter-Cellular Adhesion Molecule 1), also known as CD54, is a type of intercellular adhesion molecule constitutely present in low concentrations in the membranes of leukocytes and endothelial cells. As an endothelial and leukocyte-associated transmembrane protein, ICAM1 is well known for its importance in stabilizing cell-cell interactions and facilitating leukocyte endothelial transmigration. ICAM1 is a ligand for LFA-1 (integrin). When activated, leukocytes bind to endothelial cells via ICAM-1/LFA-1 interaction and then transmigrate into tissues. Presence with heavy glycosylation and other structural characteristics, ICAM1 possesses binding sites for a number of immune-associated ligands and serves as the binding site for entry of the major group of human Rhinovirus (HRV) into various cell types. ICAM1 also becomes known for its affinity for Plasmodium falciparum-infected erythrocytes (PFIE), providing more of a role in infectious disease.

  • N-terminal Sequence Analysis: Gln 28
  • Activity: measured by the ability of the immobilized protein to support the adhesion of PMA stimulated HSB2 human peripheral blood acute lymphoblastic leukemia cells; when cells are added to ICAM1 coated plates (12.5μg/mL, 100μL/well), approximately 55-65% will adhere specifically
  • Formulation: lyophilized in 140mM NaCl, 2.7mM KCl, 10mM Na2HPO4, 1.8mM KH2PO4, pH 7.4, 5% mannitol, 5% trehalose, 0.02% Tween®-80
  • Reconstitution: Dissolve the protein in sterile double-distilled water to a concentration of 0.2mg/mL or lower; aliquot and use as soon as possible
